FOLDING IRONING BOARD A TTORNEYS United States Patent O FOLDING IRONING BOARD John J. Toth, Bridgeport, Conn.; Minnie L. Toth, administratrix of said Jolm J. Toth, deceased Application May 6, 1952, Serial No. 286,293

' 4 Claims. (Cl. 38-117) This application is a division of my copending applicav tion Serial No. 82,199 led March 1 8, 1949, now Patent No. 2,609,628, granted September 9, 1952.

The present invention is concerned with improvements in a folding ironing board of the type described and claimed in copending application Serial No. 9,548 led February 19, 1948, entitled Ironing Board, now Patent No. 2,675,635, granted April 20, 1954.

The ironing board of this copending application comprises a pair of leaves hingedly connected together, each leaf separate from the other pivotally carrying an articulated foldable leg and also an articulated foldable strut connected between the leaf and the leg whereby the struts and legs may be extended to support the leaves in open position, or folded against the leaves and then the leaves folded to collapse the ironing board. The construction of this ironing board is such that each leg is extended or collapsed independently of the other leg, and while this has proved to be satisfactory for the purpose of rigidly supporting the ironingboard when in use, it has not maintained the board in operative position if a user should lift the board at points between its ends, for the purpose of shifting the board slightly or carrying it to another spot, since such upward pressure results in the leaves folding on each other, as occurs when the board is being collapsed, even though the legs remain locked in extended position.

An object of the present invention is to overcome the above disadvantage of collapse of the leaves when the ironing board is lifted after being set up. This object is accomplished by the provision of an improved folding ironing board having articulated legs which are interconnected so that they are extentable or collapsible simultaneously 'rather than independently of each other (and concurrently with folding or unfolding of the leaves), wherebywhen the legs are locked in extended position they also lock the leaves in open position. Thus there is prevented the collapse of the leaves when, after the board has been set up, it is lifted at points intermediate its ends, to shift or transport it.

Another object of the invention is to provide an improved folding ironing board as characterized above, in which the operations of setting up and collapsing the board may be very simple and quickly carried out, without the operator requiring detailed instructionsor any material degree of skill.

Yet another object of the invention is to provide an ,improved folding ironing board in accordance with the above, `wherein a pair of legs at one end of the board is provided with simple effective means automatically spreading them apart at their lower extremities during the setting up movement of the board.

4 A furtherobject of the invention is to provide an im- ;proved ironing board as set forth above, which is light 2,738,604 Patented Mar. 20, 1956 ICC 2 in weight and when collapsed is relatively small and compact.

Another object of the invention is to provide an improved ironing board as characterized above, in which the articulated legs and struts follow natural movements in being extended or collapsed, thereby enabling a user to easily operate the movable parts in the required manner.

Yet another object of the invention is to provide an improved folding ironing board having foldable leaves, legs, and struts, in which the opening movement of the leaves results in the legs and struts being automatically moved to an extent toward their extended positions, thereby facilitating the setting up of the board.

Still another object of the invention is to provide an improved folding ironing board in accordance with the above, which has but few parts, of simple construction, and which is accordingly simple and economical to produce.

Another object of the invention is to provide a simple and sturdy collapsible ironing board, arranged in combination with a cabinet whereby the board may be very quickly and easily set up for use, or collapsed and stored in a relatively small space available in the cabinet, in a door compartment.

In one embodiment of the invention, illustrating the combination ironing board and cabinet, the ironing board is completely removable from the storage space in the cabinet, and may be set up on its own supports and transported to any desired location.

A further object of the invention is to provide an ironing board in accordance with all of the above, which is extremely reliable in its operation over an extended period of use, and which is very stable and rm when set up for use.

A feature of the invention is the provision, in a folding ironing board, of simplified, economical means whereby the board may be easily and quickly adjusted for height.

Other features and advantages will hereinafter appear.

Referring to Figs. l and 2, an ironing board made in accordance with the invention is shown as comprising a at, top structure formed of a back leaf 11 and a front leaf 12, the leaves 11 and 12 having juxtaposed edges 13 and 14 respectively, which are connected together by a hinge 1S.

The leaves 11 and 12 are hollow, having iiat top portions and having depending anges 16 and 17 arranged so that the resulting organizations form a pair of squat boxlike structures open at their bottoms.

As shown in Fig. 3, the leaves 11 and 12 may be folded together in superposed relationship and held therein by a spring clip 18. When so folded, the tops of the leaves are separated by an intervening space 19, in which the supporting structure for the leaves is folded and disposed. When the leaves 11 and 12 are opened or aligned with each other, the juxtaposed edges 13 and 14 are in abutment together with the usual aligning pins 13' and apertures 14' and serve to position the leaves whereby they form a continuous flat and horizontal ironing surface. The anges 16 and 17 at the edges 13 and 14 may also engage each other when the leaves are open and aligned.

In accordance with the present invention, an improved extendable and collapsible supporting structure comprising articulated, interconnected legs is provided for the leaves 11 and 12, the said structure when extended supporting the leaves in operative position and when collapsed occupying the intervening space 19 between the leaves after the latter have been folded together. This supporting structure is characterized by concurrent operation of the legs, and of the legs and leaves, resulting in extreme ease and simplicity of operation and enabling the board when set up for use, to be lifted at or near its center without folding or collapsing of the leaves 11 and 12 occurring; by the utilization of natural movements whereby an unskilled person may readily set up or collapse the ironing board without requiring instructions or directions; and by extreme simplicity and ruggedness of the parts whereby the leaves 11 and 12 are held very stable and whereby the useful life of the ironing board is greatly extended.

Referring to Figs. 1 and 2 this improved, novel, leafsupporting structure comprises a pair of articulated rear legs 20 and 21 permanently pivotally secured respectively to the anges 16 of the rear leaf 11 adjacent the rear edge 22 thereof, and comprises a front articulated leg 23 having a yoke 24 connected with angularly extending divergent arms 25 which are permanently pivotally connected to the anges 17 of the front leaf 12 at points removed a slight distance from the hinged edge 14 thereof.

Each of the articulated legs 2li, 21 comprises an upper leg part 26 connected to a lower leg part 27 by a pivotal =knee joint 28. A horizontal strut 29 interconnects the lower leg parts 27. The front articulated leg 23 comprises an upper leg part 3G hingedly connected by means of a pivotal knee joint 31 to a lower leg part 32. The upper leg part 30 is preferably hollow and is rigidly secured to a shank or stud 33 of a Y-shaped connector member 34 having integral divergent fingers or studs 35 which are received in and bolted to the arms 25 forming the uppermost parts of the front articulated leg 23.

The leg parts 25 and 26 may be tubular throughout, and may be secured to the flanges 16 and 17 by fiattening the ends of the parts, perforating the ends and passing pivot studs through them as shown in Fig. 4, equipped with spring washers which compensate for wear. The tension of these springs can be regulated to control the sequence of movement of the legs.

The upper extremities of the leg parts 26 have abutting portions 36 engageable with stops 37 secured to the back leaf 11 whereby the rear legs 2t), 21 are positioned as shown in Figs. ll and 2 to properly support the leaves 11 and 12 horizontally. Also, the upper extremities of the arms 25 of the front articulated leg 23 have abutting portions 38 engageable with stops 39 secured to the anges 17 of the front leaf 12 to properly position the front leg for supporting the leaves horizontally.

It will be observed from Fig. 2 that the knee joints 2S and 31 are so arranged that the lower parts of the legs may be folded inward on the upper parts, and so that the associated parts of the individual legs may be positioned in alignment with each other when supporting the leaves 11 and 12 horizontally.

According to the invention, a novel and improved strut means is provided, interconnecting the front and rear articulated legs 20, 21 and 23 to hold the legs rmly in their extended positions supporting the leaves, and operative to enable the leg parts to be folded against each other and against the leaves when the board is collapsed. This strut means comprises a plurality of strut sections 40, 41 and 42 pivotally connected together by knee joints 43 and 44, the section 41 being located intermediate the other sections. The strut section 40 is pivotally carried by the brace 29 intermediate the ends of the latter, and the strut section 42 has a pair of arms 42a and 42b spaced from each other and at their extremities pivotally connected to the front leg part 32. The knee joints 43 and 44 are arranged to position the strut sections 40, 41 and 42 in alignment with each other when the ironing board is set up for use, and as shown in Fig. 2 the said joints enable the end strut sections 40 and 42 to be folded as shown by the broken lines, so that eventually they lie against the intermediate strut section 41 when the ironing board is collapsed.

Referring to Figs. 2 and 5, the yoke portion 24 of the front articulated leg 23 is provided with a fitting 45 having a hinged connection 46 with a manually operable locking arm 47 adapted to engage a locking projection 48 having a recess 49 for receiving the extremity of the arm 47, the said projection being immovably carried by the underside of the front leaf 12 of the board. A wire spring 50 is carried by the pivotal joint 46, and normally urges the locking arm 47 in a clockwise direction as viewed in Fig. 2. The arm 47 has a recess 51 to provide clearance for the projection 48 when the ironing board is folded, as clearly shown in Fig. 3.

In accordance with the present invention the strut 29 which connects together the pair of legs 20, 21 is so arranged and constructed that the swinging movement of the strut part 40 with respect to the legs, during the opening or setting up of the ironing board, causes the lower extremities of the legs to be spread further apart. The structure by which this is accomplished is shown in Figs. 1, 7, 8 and 10. The strut part 40 has an eye 52 which encircles and is rigidly secured to a short tubular member 53 in turn rigidly connected by pins 54 with tubular members 55 which internally receive at their juxtaposed ends the short tubular member 53. Thus the strut part 40 and eye 52 thereof, together with the tubular members 53 and 55 constitute a single, rigid assembly.

Each of the tubular members 55 carries a pair of spaced, cam members 56 which act as thread elements and are in the form of collars partially encircling the members 55. The members 56 may be made of sections of tubing, the ends of which are cut off at an inclined angle. Driving connections are established between the cam members 56 and tubular members 55 carrying the same, by pins 57 secured to the cam members and extending into short, longitudinally extending slots 58 in the tubular members 55.

Cooperable with the cam members 56 are complemen- I tary cam members 59, 59a and 60, also slidably carried on thetubular members 55 and having the form of collars partially encircling said members.

The collars 60 are rigidly connected by means of pins 61 with external tubular members or sleeves 62 which encircle and `are sldable on the collars or members 56. The cam members 59 and 59a are keyed to the sleeves 62 by means of pins 63 carried by the sleeve, extending into longitudinally extending slots 64 in the cam members.

Considering the portion of Fig. 7 to the left of the eye 52, the cam member 59, better seen in Fig. 10, is rigidly secured to a boss 65 carried by a tting 66 which is in turn secured to the leg part 27.

A spiral extension spring 67 is provided, extending through the tubular members 53 and 55, the ends of the spring being connected to the bosses 65 on fitting 66 of the leg parts 27. The extension spring 67 tends to normally urge the leg parts 27 toward each other.

It will be seen that the strut construction as set forth above is in the nature of a pair of screws and nuts, the screw parts being constituted by the tubular members 5S and cam members 56 carried thereby, and the nut parts being constituted by the sleeves 62 and cam members 59, 59a and 60 associated with the sleeves. The extension spring 67 normally tends to maintain the cam members 56, 59, 59a and 60 in engagement with each other, since all of said members except the members 60 are axially movable to a limited extent by virtue of the pin and slot connections associated with them.

The operation of the strut 29 is as follows: When the ironing board is being opened and set up for use, referring to Fig. 2, the strut part 40 will swing clockwise with respect to the sleeve parts 62 of the strut 29. Considering Fig. 7, if the eye 52 of the strut part 40 is viewed from the left end of the ligure, it would move clockwise, with respect to the sleeve 62, during the opening or setting up movement of the ironing board. This will result in the cam members 56 keyed to'the tubular member 55 traveling along the cooperable cam members 59, 59a and 60 in such a way as to shift the sleeve 62 (in the left part of the gure) toward the left. The tubular member 55 will be caused to partially emerge from the adjacent end of the sleeve 62 by virtue of such shifting, and as a con-sequence the two sleeves 62 will be caused to separate axially, thereby spreading apart the leg parts 27.

Upon the ironing board being collapsed, the reverse of the above operation will take place and the sleeves 62 will be moved axially toward each other, resuming the positions shown in Figs. l and 7.

To provide for adjusting the height of the ironing board, the parts 27 and 32 of the articulated legs telescopically receive feet 68 having a plurality of openings 69 whereby the feet may be secured, by means of screws 69a passing through the leg parts, in a number of different extended or retracted positions.

The operation of the ironing board is as follows:

Referring to Figs. l and 2, if it should be desired to collapse and fold the board from extended position, it is merely necessary to unlock the front leg 23 by moving the locking arm 47 to the left as viewed in Fig. 2, out of engagement with the locking projection 48, and then move inward or toward the leaves 11 and 12 the intermediate strut section 41. The dotted line positions of the parts indicates the result of such movement. The rear legs 20, 21 commence to fold inward with respect to the rear leaf 11, and also the lower leg parts 27 fold inward with respect to the upper leg parts 26. The lower part 32 of the front leg 23 folds inward with respect to the upper portion of the front leg, and said upper portion folds upward toward the front leaf 12. The locking arm 47 meanwhile is guided by the undersurface of the front leaf 12 and turns counterclockwise as viewed in Fig. 2 toward a position coplanar with the arms 25 of the front leg. The folding movements of the legs and struts are continued and simultaneously therewith the leaves 11 and 12 are folded, with the result that the legs and struts will nest within the folded leaves when the latter attain the position shown in Fig. 3.

To set up the ironing board, a reverse of this operation is required, that is, the leaves 11 and 12 are rst swung apart. During such movement the spring 50 will be acting on the locking arm 47 and will automatically move the arm toward its locking position. The force of the spring 50 will tend to extend the articulated legs, moving these from their positions folded against the leaves, and as ,the opening movement of the leaves is continued the legs will, by virtue of their being interconnected by the strut sections 40, 41 and 42, become further extended, whereupon the operator may grasp the intermediate strut section 41 and move it away from the leaves 11 and 12, causing the entire supporting structure to assume its fully open position. The locking arm 47 will, under the action of the spring 50 automatically engage the locking projection 48 and will lock in the recess 49 thereof, and the ironing board will be fully set up and locked, ready for use.

It will be noted that the natural inclination of a user in collapsing the ironing board is to shift the intermediate strut section 41 toward the leaves 11 and 12, and that in setting up the ironing board the natural inclination is to move the strut section 41 away from the leaves. Thus the operation of setting up or collapsing the ironing board is found to be extremely simple, and no skill or instruction is required by the operator in carrying out these operations.

Another embodiment of the invention is shown in Fig. 9, wherein a folding ironing board made in accordance with the disclosure of Figs. 1 through 8, is carried or stored in a door compartment 81 of a cabinet 82, the said compartment having a hinged panel or closure 81a.

The back end of the leaf 11b of the ironing board 80 is pivotally connected to L-shaped arms 83 of brackets 84 which have hubs or sleeves 84a carried on upright rods 85 secured to the bottom or oor surface 86 of the compartment 81. It will be understood that the front leaf 12b of the ironing board when the latter is in collapsed position, is folded against the underside of the back leaf 11b, as clearly shown in Fig. 9.

When it is desired to remove the ironing board 80 for use, the hinged panel 81u is swung open, exposing the interior of the compartment 81. The folded ironing board 80 is then swung partially downward toward horizontal position and lifted, so as to remove the brackets 84 from the rods 85 carrying them. The ironing board 80 may then be completely removed from the compartment 81 and set up for use in the manner described previously in connection with Figs. 1 through 8 and 10.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
